Benefits of technology

The patent text describes a storage device and a computing system that can improve reliability by executing firmware that corrects data errors, even if there is a power loss. This means that the system can still be trusted to store and retrieve data even in situations where there is no power available.

Problems solved by technology

When the power supply is cut off, the data is lost.

Abstract

The present technology relates to an electronic device. More specifically, the present technology relates to a storage device and a computing system. A storage device according to an embodiment may include a memory device including a firmware block group configured to store main firmware data and sub firmware data, and a user block group configured to store write data, and a memory controller, in response to a booting request provided from a host, configured to count a number of previously generated power losses based on data stored in an open block in the user block group in a booted state based on the main firmware data, performs a rebooting operation using the sub firmware data when the number of power losses exceeds a reference number, and execute sub firmware to correct an error of data related to the power losses.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority under 35 U.S.C. ยง 119(a) to Korean patent application number 10-2020-0168774, filed on Dec. 4, 2020, with the Korean Intellectual Property Office and is incorporated herein by reference in its entirety.BACKGROUNDField of Invention[0002]One or more embodiments described herein relate to a storage device and a computing system.Description of Related Art[0003]A storage device stores data under control of a host, and may include a memory controller to control a memory device. The memory device may be a volatile memory device or a nonvolatile memory device. A volatile memory device stores data only while receiving power from a power source. When the power supply is cut off, the data is lost. Examples of a volatile memory device include a static random access memory (SRAM) and a dynamic random access memory (DRAM). A nonvolatile memory device stores data even when power is cut off. Examples of a nonvolatil...
